摘要： A method for manufacturing a high-strength golf iron head with a thin striking faceplate includes placing a shell mold onto a rotary table. At least one metal ingot is placed into a crucible portion of the shell mold and melts in a vacuum environment. The rotary table rotates to cause the molten metal to flow into a cavity portion of the shell mold. The rotating shaft is slowly stopped, and the shell mold is removed after pouring. The shell mold is destroyed after the molten metal cools and solidifies, obtaining a casting. A cast product portion is separated from the casting to obtain at least one golf iron head subsequently treated with heat treatment to provide a striking faceplate of the golf iron head with a tensile strength of 280-340 ksi, an elongation of 4%-20%, and a minimum thickness of 1.4-1.8 mm excluding a groove depth of the striking faceplate.

摘要： Methods for producing a rotationally symmetrical, hollow metallic workpiece may involve rotating a casting mould about a rotation axis and introducing a melt into the casting mould. The melt may be thrown towards an inner contour of the casting mould by centrifugal forces, and hollow bodies may be added to the melt. Furthermore, a device for producing a rotationally symmetrical, hollow metallic workpiece may include a casting mould that is rotatable about a rotation axis, a feeder device for introducing a melt into the casting mould such that the melt is thrown towards an inner contour of the casting mould by the effect of a centrifugal force, and a metering device for adding hollow bodies to the melt.

摘要： A water cooling apparatus for cooling centrifugal casting equipment that includes an upper mold and a lower mold rotating together includes a rotating shaft in which a first cooling passage is formed and to which a nozzle is provided at an end portion of the rotating shaft, and a collecting portion which surrounds a side surface of the lower mold and is installed apart from the lower mold. The lower mold is connected to the rotating shaft and includes a chamber separated from a mold space formed between the upper and lower molds in order to store cooling water injected to the nozzle. The lower mold includes at least one second cooling passage extended from the chamber toward an outer circumference surface direction, and the collecting portion receives the cooling water discharged through the second cooling passage.

摘要： A method for manufacturing a low-density steel wooden golf head solves the difficulty in reducing the thickness of a conventional wooden golf head. The method includes placing a shell mold having a crucible portion and a cavity portion in communication with the crucible portion on a rotary table, placing a metal ingot into the crucible portion, followed by melting the metal ingot in molten metal in a vacuum environment, rotating the rotary table to cause the molten metal to flow into the cavity portion under a centrifugal force, gradually slowing down the rotary table after the molten metal cools and solidifies, destroying the shell mold to obtain a casting including a cast product portion, and separating the cast product portion from the casting to obtain a casting product of a wooden golf head having a density of 6.5-7.6 g/cm3 and a minimum thickness of 0.4-0.6 mm.
